A Bending Mold for U-shaped Parts of Medium-thick Orifice Plate with Asymmetrical Channel Structure

Abstract

The invention discloses a bending forming mold for a thick orifice plate U-shaped part with an asymmetric channel structure, which comprises a T-shaped force transmission part, a bending pressure head, a first rotatable support part, a second rotatable support part and a die; The mold is provided with a groove, one end of the die is connected with a first rotatable support, and the other end of the second rotatable support is connected with a second rotatable support; the first rotatable support and the second rotatable support The parts are respectively provided with down slideway grooves; the lower end of the T-shaped force transmission part is equipped with a bending indenter, and the bending indenter matches the groove. When moving to the groove, the medium-thick orifice plate to be bent is bent on one side to ensure that the overall bending deformation of the U-shaped part of the orifice plate to be bent is small and no bending cracks occur, and the flow channel is not deformed.

Description

technical field [0001] The invention relates to the technical field of bending and forming processing of medium-thick plates, in particular to a bending-forming mold for U-shaped parts of medium-thick orifice plates with an asymmetric channel structure. Background technique [0002] Nuclear fusion is an inexhaustible, clean and safe new energy that has attracted much attention. The tritium-producing cladding is the key core component to achieve plasma containment, tritium value-added and energy extraction in fusion reactors. In the cladding structure, the first wall is the part outside the cladding that directly faces the plasma. In the plasma, it serves in harsh working conditions such as high temperature, high pressure, and irradiation. Its shape, material quality, and molding accuracy directly determine the Functional and safety properties of cladding. [0003] The overall outer shape of the first wall is U-shaped, and its interior contains multiple cooling flow channel...

AI Technical Summary

Problems solved by technology

[0004] The technical problem to be solved by the present invention is that the existing manufacturing process of the first wall is difficult to meet the requirements of the size of the flow channel and the outer wall at the same time. Therefore, a bending forming mold for thick orifice U-shaped parts in an asymmetric channel structure is provided to Ensure that the overall bending deformation is small and no bending cracks occur
